Setting-Up

Assembly Instructions for the Flow Calibrators

The calibrator can be quickly attached to the battery pack by screwing

the mounting lugs into the threaded holes in the base of the calibrator.

The lugs should then be placed over the receiving holes in the top of

the battery pack and snapped gently into place. Insert the connector

from the battery pack to the receptacle in the back of the calibrator.

The calibrator is now ready to use.

Figure 2-1. Flow Calibrator Assembly

8 Chapter 3

Supplying Power

The calibrator can be powered in one of two ways: through the power

jack using the supplied 4199 battery pack or using the AC adapter.

The DC power input connector is shown below along with the power

requirements.

Power Supply: 7.5 VDC ± 1.5 V, 300 mA maximum

Connecting Filter and Flow Tubes

The Model 4048/4148 has a thermal sensor exposed to the air flow

that must be protected from foreign matter and particles. TSI supplies

a filter that should be connected to the inlet of the calibrator; however,

any filter will work as long as it has a minimum efficiency of 99.9%.

C a u t i o n

Always use a filter on the inlet of the calibrator. Failure

to filter the air flow may change the calibration and/or

permanently damage the sensor.

Note: Flow direction is identified by the large arrow printed on the bottom side of the calibrator and on the bottom of the battery pack.

Attach the filter to the inlet of the calibrator using supplied tubing

and/or adapters. Connecting a tube to the outlet of the calibrator will

create back pressure. See Appendix A for calibrator accuracy

specifications when operating at various pressures. In general,

minimize back pressure on the calibrator by using shorter lengths of

tubing to maintain highest level of accuracy.

Chapter 3

Operation

Overview

The Model 4048/4148 Flow Calibrator measures volumetric flow rate

inside the flow tube. All measurements made by the Models

4048/4148 are NIST traceable.

ON/OFF Switch

Slide the switch to the ON position. The LCD displays volumetric flow

in units of liters per minute (L/min).

Flow Rate Measurement

Flow rate data will be displayed on the Model 4048/4148 through the

LCD.

Volumetric flow is displayed in units of liters per minute (L/min).

Setting Flow Rates and Calibrating Instruments

The Model 4048/4148 Flow Calibrator may be used to measure or set

flow rates on Condensation Particle Counters or other instruments

which draw an active flow sample. Be sure to follow all instrument

manufacturer’s flow setting and calibration procedures.

1. Start up the Model 4048/4148 Flow Calibrator and let it warm up

(1 minute for Model 4048 or 10 minutes for Model 4148) prior to

setting any flow rates or conducting any calibrations.

2. Connect the outlet of the Model 4048/4148 Flow Calibrator to the

inlet of the active sampling instrument.

NOTE: Please contact TSI Technical Support at 800-874-2811 for instructions on connecting Model 4048 to TSI Filter Testers.

3. Follow the instrument manufacturer’s flow setting and/or

calibration procedures. The volumetric flow in units of liters per

minute (L/min) will be continuously displayed on the LCD of the

calibrator.

Chapter 4

Maintenance

Flow Sensor

Periodically inspect the flow sensor by looking into the outlet of the

calibrator. Remove dust, particles and fibers from the sensor with

clean, dry compressed air. The flow sensor may break if touched.

Never run liquids through the calibrator and never touch the

sensor with a brush. Dust or other deposits on the flow sensor will

degrade the Model 4048/4148’s flow accuracy.

C a u t i o n

The calibrator must be switched off for cleaning. Only

use clean, dry, compressed air when attempting to

remove contamination from the sensor.

Re-certification

To maintain a high degree of confidence in the measurements made

by the Model 4048/4148, TSI recommends that the instrument be

returned to TSI every 12 months for re-certification. The calibrator will

be recalibrated and returned with a certificate of calibration to US

National Institute of Standards Technology (NIST) traceable

standards.

Cases

If the instrument case or storage case needs cleaning, wipe it off with

a soft cloth dipped in isopropyl alcohol or mild detergent. Never

submerge the calibrator or allow liquids to enter the flow tube.

Storage

When storing the calibrator, always cover the ends of flow tubes with

the caps provided to prevent dust or other foreign matter from

entering the tube.
